STANCHION.

SPECIFICATION forming part of Letters Patent No. 401,307, dated April 9, 1889.

Application filed February 18, 1838- Serial No. 263,914. (No model.)

To ctZZ whom it may concern:

Be it known that I, ALTER SCOTT, a citizen of the United States, residing at Hoosick Falls, county of Rensselaer and State of New York, have invented certain new and useful Improvements in Cattle-Stanchions, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in cattle-stanchions; and it consists in a novel locking mechanism, whereby the animal in reaching its head. downward to get the food in the manger locks itself in the stanchion.

Referring to the accompanying drawings, in which similar letters of reference indicate like parts, Figures 1 and 2 are elevations of my improved stanchion, showing it open, ready to receive the animal, and closed, respectively. Fig. 3 is a perspective of the locking device; and Fig. i, a perspective View, broken away, showing the attachment of the iZpring which operates the pivoted stanchion- A A are two upright timbers secured to the cross-timbers B B at the head of the stall, and the food-rack is placed behind the beams A A. The stanchion is pivoted in the cross-beams B B by the pins if. The pin 2' is secured to the upper horizontal cross-bar, E, of the stanchion and passes through a block, I, interposed between the beam B and cross-bar E, to permit the latch H to be swung upward. The lower crossbar, F, is beveled to permit it to turn more easily on the lower cross-beam, B, and the pins 'L' f being opposite one another the stanchion is permitted a swinging movement to allow the animal to turn its head. The vertical bar 0 is bolted at c c to the opposite ends of the cross-bars E and .F. The cross-bar E is extended beyond the lower bar, F, and a longitudinal slot, e, is out into such extension. In the outer end of the slot 6, at h, is pivoted the gravity-latch H. The lower crossbar, F, is slotted at f to receive the pivoted bar D, pivoted by the bolt f at its inner lower corner in the slot f" A notch,d is cut out in the other lower corner of the bar D, and a spring, K, is interposed between the bolt f secured in the bar F, and the pivoted bar D, fitting in the notch (1 The lower ends of the bars C and D are secured to the bar F at the proper distance apart to confine the animals head. The upper end of bar D slides in the slot 6 in the upper horizontal bar, E, and is formed with the shoulder (l on the side adjacent to the latch H. The upper end is also beveled at d to decrease the friction be tween D and H, either in closing or opening the stanchion.

The block J is bolted to the upright C, and is formed with the shoulder j. To the bar D is pivoted at g the prop G, abutting against the shoulder j.

The operation of myinvention is as follows: The bar D being swung on its pivot f away from the bar G, the spring K is compressed, and the prop G being swung up against the shoulder j the force exerted by the spring holds it there, maintaining the bar D in the position shown in Fig. 1, the gravity-latch H resting upon the top of the bar. The animal puts its head between the bars 0 D above the prop G, and in reaching down into the manger releases the prop, which swings down to position shown in Fig. 2, out of the way, when the spring K moves the bar D up against the end of the slot 6 and the latch H falls down into the shoulder at and prevents the bar D from being moved back until the latch is raised. W'hcn the animal is released, it is only necessary to raise up the latch H, swing the bar D back, and raise up the prop G against the shoulder j, and the stanchion is set.

It is obvious that a leaf-spring might be attached to the bars D and F instead of using the spiral spring K, and the same result would be obtained.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the pivoted stanchion-bar and a prop adapted to hold the said bar open against the action of a spring and to be swung downward by the animal to perunit the spring to close said bar, of a locking device operated by the movement of the pivoted bar to hold the animal in. the stanchion, substantially as and for the purpose In witness whereof I have hereunto set my specified. hand this 11th day of February, 1888.

2. The combination, with the elon 'ated bar 1 1 E, latch H, pivoted in the slot e and r esting on TALTER 5 the top of the pivoted bar D, of the prop G W itnesses:

and spring K, substantially as and for the pur- DANFORTH GEER,
